Open up this advent calendar of terror, for the 25 spine tingling days of Christmas. Unsettle in, for a Christmas feast that will be served chilled... to the very bone. We all love a good Christmas ghost story or horror movie. If Hammer House of Horror, Tales of the Unexpected and Pans Books of Horror set your pulse racing and mind spinning as a youngster, then these stories, set at Christmas, offer the darkest recesses of your mind, a deliciously macabre feast in which to indulge itself.
